  • Page 21: External Inputs

    Of these 3 external inputs, Ch 1 and Ch 2 are routed via the TCH002 T-cube controller hub, allowing the TPZ001 to be controlled by other cubes on the hub. For example, a combination of a TPZ001 unit with a TSG001 Strain Gauge Reader allows closed loop operation, or two TPZ001 units with a TNA001 NanoTrak cube allows optical beam alignment.
  • Page 22 Note. This setting applies only to open loop mode, where using an external signal to control the TPZ001 is optional. Closed loop operation is only possible if there is an external feedback signal connected to the unit, so the selected external input is always assumed to have a signal source driving it.

    This tutorial shows how the Kinesis application provides all of the functionality necessary to operate the hardware. 1) Power up the hardware, and wait until the TPZ001 has finished booting up, then run the Kinesis software - Start/All Programs/Thorlabs/Kinesis/Kinesis. Note For maximum accuracy, wait approximately 30 mins for the unit to thermally stabalize to the environment.

  • Page 24: Introduction To Open And Closed Loop Operation

    For the Thorlabs range of piezo actuators, the TSG001 strain gauge reader is a fully self contained unit that is designed to work with the TPZ001 in closed loop mode, providing the feedback signal necessary for closed loop operation.

    T-Cube Piezo Driver 5.4.3 Using the Controller as a Piezo Amplifier Certain applications may require the piezo to be driven by a voltage generated from an external source (e.g. a signal generator). The piezo T-Cube is designed to accept an external 0 to 10V signal and handle the amplification from 10V to 75 or 150V. As an example, the following procedure explains how to configure the unit as a piezo amplifier.
